First, L eslie demonstrates how to make the classic pie dough that will form th e base of these desserts; some of the dough is used raw, while other c rusts are pre-baked in order to avoid a soggy crust. This dough can be frozen for up to a month. Once the shells are prepared, she creates a classic French apple tart, a berry yogurt tart, and a blueberry necta rine tart garnished with chopped almonds.
